Flexible Diaphragms

[erenattos]

hi folks, i´d llike to know how can i modelate a flexible floor concrete diaphragm in ETABS

AS far as I know, you just need to create a shell property in "Define" "Wall/Slab/ sections"

The shell element should have the appropiate material properties and thickness

hope this can help

In a change from previous versions, from V7 ahead, flexible diaphragms are the default in ETABS. If you desire a rigid diaphragm you have to define it explicitly. So, essentially, if you do nothing you will end up with a "flexible" floor diaphragm.
